I tend to book unpopular cruises, i.e. repos because I love them as a means of transportation. Prices tend to drop on these though TATLs are not as cheap as they once were and TPACs never were.
That said, I booked a repo to get me home from the LGB area end of the month. Cruiseco was asking a minimum of $500 for the longest time until sales department got serious in January and started to lower the price, dropping to USD 169 for all cheap cabins (internal, window and balcony grades) last week. Booked a GTY and was assigned a cabin that someone on drugs would pay that much for (USD330 for a 4 night cruise?)
Sitting in H.K. right now waiting to, hopefully, board a ship to take me TPAC in a few hours.
